The SCIENTICO FrizoDynamics FX-522 Bearing Friction Apparatus is a wall-mounted experimental unit for the determination and comparison of friction torque in plain sliding bearings and rolling bearings under identical loading conditions. A 300 mm galvanised steel flywheel of 22.2 kg provides the bearing load through its own dead weight, eliminating the need for a separate loading mechanism. Three sets of interchangeable sliding bearing shells — gun metal, cast iron, and PTFE — and a Type 6203 grooved ball bearing allow four bearing configurations to be tested on the same stainless steel shaft. Friction torque is determined by adding dead weights via a cable drum and hanger until the flywheel just begins to rotate, with the onset-of-motion load directly corresponding to the bearing’s frictional torque. With rolling bearings installed, the flywheel additionally supports fundamental rotational dynamics experiments. Suitable for undergraduate machine elements, tribology, and mechanical engineering laboratories, the FX-522 is supplied complete with all bearing sets, weight set, hanger, thread, and instructional manual. Manufactured by SCIENTICO, available for institutional supply and international distribution.

The SCIENTICO FrizoDynamics FX-519 Belt and Cord Friction Apparatus is a portable, bench-mounted unit for the experimental determination of friction coefficients in belt drive systems and the verification of Eytelwein’s rope friction formula. A 150 mm anodised cast iron pulley, ball bearing-mounted and fitted with three grooves, accommodates a flat belt (leather/polyamide, 15 x 2.2 mm), a V-belt (ISO 4184 A-type, rubber/fabric), and round belts (rubber, 8 mm and 10 mm). The contact angle is adjustable from 30° to 210° in 30° increments, and two calibrated weight sets establish the tight-side and slack-side tensions for friction coefficient calculation. Flat belt versus V-belt versus round belt friction comparisons and the effect of incorrect belt alignment can both be investigated on the same apparatus. No power supply is required. Suitable for undergraduate machine elements, tribology, and mechanical engineering laboratories, the FX-519 is supplied complete with all belt types, weight sets, thread, and instructional manual. Manufactured by SCIENTICO, available for institutional supply and international distribution.

The SCIENTICO FrizoDynamics FX-518 Coriolis Force Apparatus is a self-contained bench-top unit for the direct visualisation of the Coriolis effect in a rotating reference frame. A submersible pump mounted in a transparent water tank on a rotating arm projects a radial water jet at up to 2 L/min. When the arm is stationary the jet travels in a straight radial line; when the arm rotates at speeds up to 60 rpm, the jet deflects from this reference path in a direction and magnitude dependent on the rotation speed and direction — directly observable on the graduated scale on the tank. Reversing the rotation direction reverses the deflection, demonstrating the vector nature of the Coriolis force. A closed water circuit eliminates the need for an external supply, and a digital speed sensor confirms the arm rotation rate throughout the experiment. Suitable for undergraduate and postgraduate dynamics, rotational mechanics, and geophysics laboratories, the FX-518 requires only a standard power supply and is supplied complete with power cord and instructional manual. Manufactured by SCIENTICO, available for institutional supply and international distribution.

The SCIENTICO FrizoDynamics FX-515 Two Arm Lever Apparatus is a bench-top statics unit for the experimental study of moment equilibrium on a centrally pivoted beam. The 600 mm beam — mounted on precision ball bearings at its midpoint and graduated along its full length — provides two 300 mm lever arms on which three riders with hooks can be positioned at any scale point. Known weights are applied to each rider, and students adjust load positions and magnitudes to achieve rotational equilibrium, directly verifying the law of moments. The ball bearing pivot ensures high sensitivity to moment imbalance, making the unit suitable for precise quantitative experiments as well as introductory demonstrations. A comprehensive weight set covering 0.5 N to 5 N denominations supports a wide range of loading combinations. Manufactured by SCIENTICO, available for institutional supply and international distribution.

The SCIENTICO FrizoDynamics FX-514 Forces in Truss Apparatus is a fully instrumented structural mechanics unit for the experimental measurement of bar forces in single-plane statically determinate trusses. Bars in six lengths — from 150 mm to 520 mm — are assembled using pin-jointed node discs within a rigid support frame, allowing three distinct truss configurations to be constructed. Each bar carries an individual strain gauge load cell, and all 12 channels are acquired simultaneously by the measurement amplifier and processed by dedicated LabVIEW-based DAQ software, which displays bar forces graphically in real time. A load application device (−500 to +500 N, 0.01 N graduation) applies a controlled external force at any node disc, and its position and direction can be varied to investigate load dependency. Measured results are compared directly against the method of joints and Ritter’s method of sections. All components are housed in a dedicated storage system. Manufactured by SCIENTICO, available for institutional supply and international distribution.

The SCIENTICO FrizoDynamics FX-511 Toggle Joint Apparatus is a bench-top mechanics unit for the experimental study of force distribution and reaction forces in a three-member toggle joint under applied vertical loading. The opening angle is continuously adjustable between 30° and 135°, and a mechanical spring balance (0–10 kg, 50 g graduation) measures the horizontal reaction force at the moveable end of the base member directly under load. Students resolve forces analytically at the toggle apex and compare calculated values against spring balance readings across a range of angle and load combinations, building a quantitative understanding of the force amplification behaviour characteristic of toggle mechanisms. The unit is of solid metal construction, requires no wall mounting, and is supplied complete with weight set, chain, measuring tape, and instructional manual. Manufactured by SCIENTICO, available for institutional supply and international distribution.

The SCIENTICO FrizoDynamics FX-510 Forces in a Jib Crane Apparatus is a wall-mounted structural mechanics unit for the experimental determination of compressive and tensile forces in a two-member crane structure. A force gauge integrated into the jib (0–100 N, 0.5 N graduation) and a spring balance integrated into the tie (0–10 kg, 50 g graduation) provide direct force readings under applied dead loads. Students compare measured results against theoretical values derived from the triangle of forces and polygon of forces methods, verifying static equilibrium principles in a physically clear and historically relevant structural form. Both the jib overhang and tie inclination are adjustable, enabling experiments across multiple geometric configurations. The unit folds flat when not in use and is supplied complete with weight set, hanger, chain, measuring tape, and instructional manual. Manufactured by SCIENTICO, available for institutional supply and international distribution.

The SCIENTICO FrizoDynamics FX-506 Rolling Disc on Inclined Plane is a bench-top dynamics apparatus for the experimental determination of moment of inertia through both rolling and pendulum test methods. Two steel discs — 380 g at 70 mm diameter and 650 g at 100 mm diameter — are rolled down a precision-aligned inclined track of up to 1000 mm, with inclination adjustable from 0° to 10° and confirmed by a built-in inclinometer. Integrated spirit levels, a three-point support system, and self-centering conical disc pins ensure consistent, repeatable experimental conditions. The unit covers a broad range of rotational dynamics experiments including the law of gravity on an inclined plane, influence of mass on acceleration, and proof of the law of falling bodies. Suitable for undergraduate and postgraduate mechanical engineering and physics laboratories, the FX-506 is supplied complete with stopwatch, lock pin, and instructional manual. Manufactured by SCIENTICO, available for institutional supply and international distribution.

The SCIENTICO FrizoDynamics FX-504 Centre of Gravity Apparatus enables students to experimentally determine the centre of gravity of six flat lamina shapes — circle, isosceles triangle, trapezium, L-shape, T-shape, and semi-circle — using the plumb bob method. Each lamina is suspended from a pin on a free-standing backboard, a plumb bob defines the vertical line of action of its weight, and the process is repeated from a second hole. The intersection of the resulting lines locates the CG, which is then compared against values from calculation or standard reference books. The experiment clearly demonstrates that for compound shapes such as the L and T sections, the CG may fall outside the physical boundary of the object — a result that is difficult to visualise analytically but immediately apparent through experiment. Designed for statics and solid mechanics laboratories, the FX-504 is supplied complete with six lamina samples, plumb bob, thread, and instructional manual. Manufactured by SCIENTICO, available for institutional supply and international distribution.

The SCIENTICO FrizoDynamics FX-503 Three Wire Suspension Apparatus enables students to study force equilibrium in two-wire and three-wire suspension systems. Known loads are applied to a common node ring from which three wires radiate at angles of approximately 45°, 60°, and 90° to the horizontal. The tension in each wire is read directly from integrated linear spring balances, and students verify that the resolved horizontal and vertical force components sum to zero under each applied load. The apparatus also supports investigation of the redundant vertical tie — introducing students to statical indeterminacy in a clear, measurable context. Wire lengths are individually adjustable via threaded rods, allowing accurate geometry setting before each experiment. Designed for statics and structural mechanics laboratories, the FX-503 is supplied complete with three spring balances, node disk, calibrated weight set, and instructional manual. Manufactured by SCIENTICO, available for institutional supply and international distribution.

The SCIENTICO FrizoDynamics FX-500 Rubber Shear Apparatus allows students to study the shear deformation of a rubber block under incrementally applied dead loads. Using a precision dial gauge with 0.01 mm resolution, users measure deflection at each load step and derive the modulus of rigidity, shear stress, and shear strain for the rubber specimen. The apparatus also demonstrates hysteresis — the non-linear recovery behaviour of rubber during unloading — connecting theory to real-world applications in vibration isolation and flexible mounting. Suitable for undergraduate and postgraduate mechanical engineering laboratories, the FX-500 is supplied complete with a calibrated weight set and instructional manual. Manufactured by SCIENTICO, available for institutional supply and international distribution.
